[mkgmap-dev] New, faster splitter

From Chris Miller chris_overseas at hotmail.com on Sat Jun 5 14:32:33 BST 2010

WanMil sent through a very nice patch for the splitter that writes out the 
results using multiple threads, giving a pretty big speedup during the 2nd 
half of the split if you have a multicore PC. For me, the time it takes to 
split the UK is less than half what it used to be.

I've checked his patch in (r109) so feel free to give it a go. Note that 
by default the code will automatically use all available CPU cores but there's 
a new parameter --max-threads that you can use to control the number of cores 
that are used should you want to reduce them for whatever reason.
